Next task: A-B-A test and weather-proof it. Weigh it, measure it, to answer those inevitable questions.
Many thanks for sharing the results. This is just what we need to help understanding.

As you mentioned the current curvature on the sides is not ideal. Do you have a picture of the boat-tail from above & (ideally) the angles used? This will help determine what angles to not exceed.
